Copper Color HSV Code
The Copper HSV code is 18°, 53%, 85%. Read it as a hue of 18 degrees, 53% saturation and 85% value, which is the form most color pickers use because moving one number changes one thing.

Copper Color CIELChuv Code
The Copper CIELCHuv code is 65.01, 68.38, 29.54°. Unlike hex or RGB this one is perceptual: lightness 65 means mid-toned to the eye rather than to the screen, and chroma 68 is how far it sits from grey.

What are Copper Color Palette Codes?
Each of these is a hue rotation from #DA8A67. They are generated, not curated, so they are exact.
Complementary
Directly opposite sits #67B7DA, a light, saturated azure blue. No other pairing separates two hues further, so this is the one to reach for when a single element has to win attention. Neither is especially saturated, so this pairing stays calm enough for large areas of both.
Analogous
#DA677E and #DAC467 sit 30 degrees either side. All three share most of their hue, so the set reads as one family instead of three separate decisions. Good for backgrounds and for state variations that should not announce themselves.
Triadic
#67DA8A and #8A67DA complete an even 120 degree split. Three fully independent hues, so one has to lead: keep this base dominant and let the other two appear in small quantities.
Split-complementary
Instead of the direct complement, this takes the two hues either side of it: #67DAC4 and #677EDA. Almost the same contrast, without the edge shimmer a true complementary pair produces at high saturation.
Tetradic
Two complementary pairs forming a rectangle: this base with #67B7DA, and #7EDA67 with #C467DA. The richest of the five and the hardest to balance, so treat the darkest of the four as the lead and hold the other three well back.
Accessibility
Contrast checker: is Copper accessible?
Measured against white and against black, with a separate verdict for each element type. Small text, large text and UI components have different thresholds, so one pass or fail for the whole color would be wrong roughly a third of the time.
White background
2.69:12.69
contrast ratio on white background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Fails | Fails |
| Large text needs 3:1 / 4.5:1 | Fails | Fails |
| UI component needs 3:1 | Fails | n/a |
Black background
7.81:17.81
contrast ratio on black background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Passes | Passes |
| Large text needs 3:1 / 4.5:1 | Passes | Passes |
| UI component needs 3:1 | Passes | n/a |
At 2.69:1 against white, Copper is a fill color rather than a text color. Use it for surfaces, borders and large display type, and set the copy in ink. Text placed on it should be black, which gives 7.81:1.
Color vision
How Copper looks with color blindness
Around 300 million people see color differently from the way it is specified. Each card shows the actual color beside how it appears, and how common that form of vision is.
Protanopia
About 1% of men#BDBC71
Copper changes substantially here. ΔE 39.5
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#C1C673
Copper changes substantially here. ΔE 43.9
No working green cones. With the milder deuteranomaly at nearer 6% of men, this is by far the most common form, and the one worth designing around.
Tritanopia
About 1 in 10,000#D77879
Copper shifts noticeably here. ΔE 18.9
No working blue cones. Blues shift toward green and yellows toward pink. Rare, and unlike the others it is not sex-linked, so it affects men and women equally.
Achromatopsia
About 1 in 30,000#9E9E9E
Copper changes substantially here. ΔE 41.4
No color vision at all. Also a fair proxy for how the color survives a greyscale print or a failing screen.
To a deuteranope, the most common form, Copper reads as #C1C673. That is a shift of ΔE 43.9, so it is a different color to roughly one man in sixteen. It sits in the red end of the spectrum, which is exactly where red-green deficiency does its damage. Never pair it with a green of similar lightness to signal a difference in meaning: to a large minority the two become one color. The widest shift is under deuteranopia, at ΔE 43.9. The rule this leads to needs no simulator: never let color be the only thing carrying a message. Add a label, an icon, or a clear difference in lightness, and the problem disappears for everyone.
